InSight’s robotic-arm takes an image of the Martian surface of Elysium Planitia.

The Jet Propulsion Laboratory released audio clips of the alien wind after the low-frequency rumblings were collected by the InSight lander during its first week of operations at Mars.

NASA’s Jet Propulsion Laboratory released audio clips of the alien wind Friday. The low-frequency rumblings were collected by the InSight lander during its first week of operations at Mars.

The wind is estimated to be blowing 16 kph to 24 kph (10 mph to 15 mph). These are the first sounds from Mars that are detectable by human ears, according to the researchers.

The noise is of the wind blowing against InSight’s solar panels and the resulting vibration of the entire spacecraft, recorded by an air pressure sensor inside the lander that is part of a weather station, as well as the seismometer on the deck of the spacecraft.

The seismometer itself is meant to detect underground seismic waves, well below the threshold of human hearing and will be moved to the Martian surface in the coming weeks. Until then, the team plans to record more wind noise.
